disposeFusionCharts() - drag&drop events not cleared

Recommended Posts



I am trying to use a 'MSColumn3D' chart from FusionCharts (version 3.3.1-sr2.19840).

It works fine for display.


Then I need to use disposeFusionCharts() to destroy the chart and free used ressources.

Chart disapear from screen and dom elements are removed : good


But after that, if I click on a div of a component not related to FusionCharts (header of a custom modal message box), a javascript error appear : Uncaught TypeError: Cannot call method 'call' of undefined

Using the console, I discover that a drag&drop event is still lauching some FusionCharts methods (hijack() in FusionCharts.HC.js).


Same error appear when moving mouse inside a complex grid (where drag&drop can be used).


So it looks like  disposeFusionCharts() is not cleaning everything.


Could you have a look ?
